Museum-grade sample.
In early 2004 Max Whitby and I started selling individual element samples identical or similar to the samples we use in the museum displays we build. These are top-quality samples presented in attractive forms appropriate to the particular element. They are for sale from Max's website and also on eBay where you will find an ever-changing selection of samples (click the link to see the current listings).
This ingot shows two kinds of surfaces, one where the metal cooled in contact with a graphite mold, and the top that was in contact with the air. The top surface is particularly interesting in that it shows the crystal structures that give the surface a wrinkled appearance.Source:Theodore GrayContributor:Theodore GrayAcquired:6 March, 2004Text Updated:11 August, 2007Price: See ListingSize: 4"Purity: >99%Sample Group:RGB Samples
